Mailgun MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Mailgun and the rest of your systems. It gives your agent 275 Mailgun actions (118 reads, 100 writes and 57 that wait for a confirmation) and holds the Mailgun credential itself, so the agent never does. It paces Mailgun's limits and records every call.

Set up

Connect Mailgun in three steps.

  1. 01

    Add actionlake to Claude.

    Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.

    https://connect.actionlake.com/mcp
  2. 02

    Connect Mailgun.

    Username and secret. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key.

    • api_hostWhere your Mailgun lives: your api host

# free: exactly what to paste, and what is found for you
  3. 03

    Make the first call. Check before a write.

    Ask in plain words; Claude picks the action. Before anything changes, check validates the call and prices it, for free.

Top actions

The Mailgun API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 108 of Mailgun's 117 action names are shared with at least one other connector, so an agent learns them once.

Governance for Mailgun

Destructive actions wait for a yes.

57 Mailgun actions are destructive. The first 10:

  • Delete a mailing listmailgun.lists.delete
  • Delete a mailing list membermailgun.lists.members.delete
  • Delete a domain templatemailgun.templates.delete
  • Delete all domain templatesmailgun.templates.delete_all
  • Delete an account templatemailgun.account_templates.delete
  • Delete all account templatesmailgun.account_templates.delete_all
  • Delete a bouncemailgun.bounces.delete
  • Delete a complaintmailgun.complaints.delete
  • Delete an allowlist entrymailgun.whitelists.delete
  • Delete all bouncesmailgun.bounces.delete_all

A destructive action runs only with confirm: true. Under the human policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

Questions

The Mailgun MCP server, answered.

Is there a Mailgun MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 275 Mailgun actions across infrastructure, account, domains and templates, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Mailgun.

What do I need to connect Mailgun?

Mailgun API key. Plus your api host. The free call account { op: "connections.requirements", service: "mailgun" } lists exactly what to paste.

Can an AI agent delete or change things in Mailgun?

Only if its key allows it, and only with an explicit confirmation. 57 Mailgun actions are destructive, including delete a mailing list, delete a mailing list member and delete a domain template. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

Will an AI agent use up my Mailgun API limit?

actionlake paces every call to the limits in the Mailgun service file: 300 calls a minute, at most 10 at a time per connection. Repeated reads are answered from cache (116 Mailgun actions can be), which never reaches Mailgun.

What does a Mailgun action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (30 Mailgun actions page). Cache hits, searches, dry runs and calls Mailgun refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which Mailgun API does it cover?

The Mailgun Email API API v3/v4/v5 at your Mailgun instance's API base URL, which you enter when connecting. It is built from Mailgun's documentation as read on 19 September 2026. 275 actions in 13 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my Mailgun data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to an hour, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Mailgun credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
